About Ipratropium Bromide: Ipratropium is used to control and prevent symptoms (wheezing and shortness of breath) caused by ongoing lung disease (chronic obstructive pulmonary disease-COPD which includes bronchitis and emphysema). Show more ▾

It works by relaxing the muscles around the airways so that they open up and you can breathe more easily. Controlling symptoms of breathing problems can decrease time lost from work or school.

Use your quick-relief inhaler (such as albuterol, also called salbutamol in some countries) for wheezing or sudden shortness of breath unless otherwise directed by your doctor. Ipratropium does not work as fast as your quick-relief inhaler, but may sometimes be used to relieve symptoms of wheezing or sudden shortness of breath if so prescribed by your doctor. A muscarinic antagonist structurally related to ATROPINE but often considered safer and more effective for inhalation use. It is used for various bronchial disorders, in rhinitis, and as an antiarrhythmic.

About Trelegy Ellipta: This product is used to control and prevent symptoms (such as wheezing and shortness of breath) caused by asthma and ongoing lung disease (chronic obstructive pulmonary disease-COPD, which includes chronic bronchitis and emphysema). Show more ▾

Controlling symptoms of breathing problems helps you stay active. This inhaler contains 3 medications: fluticasone, umeclidinium, and vilanterol. Fluticasone belongs to a class of drugs known as corticosteroids. It works by reducing swelling of the airways in the lungs to make breathing easier. Umeclidinium belongs to a class of drugs known as anticholinergics and vilanterol is a LABA medication. Both drugs work by relaxing the muscles around the airways so that they open up and you can breathe more easily. Both drugs are also known as bronchodilators. When used alone, long-acting beta agonists (such as vilanterol) may rarely increase the risk of serious (sometimes fatal) asthma-related breathing problems. However, combination products containing both an inhaled corticosteroid and long-acting beta agonist, such as this product, do not increase the risk of serious asthma-related breathing problems. For asthma treatment, this product should be used when breathing problems are not well controlled with two asthma-control medications (such as inhaled corticosteroid and long-acting beta agonist) or if your symptoms need combination treatment. This medication must be used regularly to be effective. It does not work right away and should not be used to relieve sudden shortness of breath. If sudden breathing problems occur, use your quick-relief inhaler as prescribed.

In 2023, this provider wrote 17 Medicare prescriptions for Trelegy Ellipta, about a third of the volume of the typical Arizona prescriber of this medication (57). Medicare paid an average of $913.32 per fill, versus $909.86 statewide.

About Breo Ellipta: This medication is used to prevent and decrease symptoms (wheezing and trouble breathing) caused by asthma and ongoing lung disease (chronic obstructive pulmonary disease-COPD, including chronic bronchitis and emphysema). Show more ▾

This inhaler contains 2 medications: fluticasone and vilanterol. Fluticasone belongs to a class of drugs known as corticosteroids. It works by reducing the swelling of the airways in the lungs to make breathing easier. Vilanterol belongs to a class of drugs known as long-acting beta agonists. It works by relaxing the muscles around the airways so that they open up and you can breathe more easily. When used alone, long-acting beta agonists (like vilanterol) may rarely increase the risk of serious (sometimes fatal) asthma-related breathing problems. However, combination inhaled corticosteroid and long-acting beta agonists, such as this product, do not increase the risk of serious asthma-related breathing problems. For asthma treatment, this product should be used when breathing problems are not well controlled with one asthma-control medication (such as inhaled corticosteroid) or if your symptoms need combination treatment. Before using this medication, it is important to learn how to use it properly. This medication must be used regularly to be effective. It does not work right away and should not be used to relieve sudden asthma attacks.

About this data. The prescription history for ALEXEI GONZALEZ ESTRADA MD is compiled from the Centers for Medicare & Medicaid Services (CMS) Medicare Part D Prescriber Public Use File for calendar year 2023, the most recent federal release. Figures cover prescriptions filled for Medicare Part D beneficiaries only; prescriptions under private insurance, Medicaid, or self-pay plans are not included. Because prescribing decisions are generally consistent across coverage types, this record offers a useful view of the overall Allergy & Immunology prescribing approach at this Scottsdale, AZ practice.

Reading the costs. Drug costs are gross amounts paid to pharmacies under Part D, including both plan and beneficiary payments. They are not the price a patient pays at the pharmacy counter. Medications with fewer than 11 claims are excluded from the federal source data, and state comparisons use the average volume among AZ prescribers of the same medication. Always confirm current medications and costs directly with the provider and your plan.
